Abstract

This research is a quasi-experimental research by obtaining relevant information for the problems studied and using objective analysis to obtain valid conclusions. For data collection tools, tests and observations are used. From the results of the pre-test, 34 students have not succeeded in understanding the set material. Meanwhile, 6 students have managed to understand the set material. Judging from the average initial ability of students before the set material was taught, it was 47.38. So the level of student mastery on the set material with conventional learning is very low. After learning with Reciprocal Teaching, it was found that 2 students had not succeeded in understanding the subject of the volume of cubes and blocks. Meanwhile, 38 students have succeeded in understanding the set material. Judging from the average initial ability of students before the application of the Reciprocal Teaching learning model on the set material, that is 47.38 and after making improvements to the learning outcomes, the data obtained is 80.13, then the comparison of students' mastery levels on the set material can be improved, namely the category is good. Based on the results of the study, it can be concluded that there is an increase in students' creative thinking skills who are taught after applying the Reciprocal Teaching learning model to the set material in class VII MTsS Utama Nagasaribu for the 2020-2021 academic year.

Abstract

One thing that must be developed in learning mathematics is students' motivation and interest in learning, because motivation and interest in learning have an important role in determining student success. This study aimed to determine whether there is an effect of student motivation and interest in learning on learning outcomes on the subject of linear equations of one variable. The population in this study were seventh grade students of SMP Negeri 9 Padangsidimpuan, with a total of 8 classes of VII class. In this study, the sample was taken from the population using the Cluster Random Sampling technique, namely the research took the sample based on a predetermined population area. The number of samples is 32 students. The data collection method used in this study is a questionnaire and documentation method. For the final data analysis using multiple Linear Regression. The results of the study obtained that the estimation equation for multiple linear regression for all students was = 39 + 0.79 + 1.02 with a partial correlation coefficient of 0.490, indicating a relationship between student motivation and learning outcomes in mathematics. The positive correlation coefficient value indicates that the relationship between motivation and learning outcomes is unidirectional. Partial correlation coefficient of 0.293, this indicates a relationship between student interest in mathematics learning outcomes. The positive correlation coefficient value indicates that the relationship between interest and learning outcomes is unidirectional. After the partial correlation coefficient was tested for significance, it turned out that both coefficients were significant, meaning that the relationship between student motivation and learning outcomes in mathematics if interest remained significant.

Abstract

The research method used was classroom action research using two cycles carried out in the first semester with SPLDV material. The sample in this research was 36 students in class X Office Automation and Management at SMK Negeri 1 Aek Nabara. The class used as a sample is class X Office Automation and Management at SMK Negeri 1 Aek Nabara which will use Power Point media in learning. The results of the research show that the ability of students' learning outcomes in learning Mathematics through the PowerPoint media learning model for class , then increased to 88.55 in the "Good" category in cycle II. The results obtained in cycle II showed that the expected categories had been fulfilled, namely with an average score of 75 and classical completion of 75% of students getting a minimum score of Good.

Abstract

Penelitian ini merupakan penelitian kuantitatif dengan metode eksperimen. Populasi penelitian ini adalah keseluruhan siswa kelas MTs. Muhammadiyah 22 Padangsidimpuan yang terdiri dari 3 kelas sebanyak 76 siswa, dua kelas ini akan digunakan sebagai sampel penelitian. Kelas kontrol sebanyak 25 siswa dan kelas eksperimen 25 siswa. Instrumen yang digunakan sebagai pengumpul data adalah tes yang diberikan sebanyak dua kali, yaitu pretest dan postest. Sedangkan untuk pengolahan data dan analisis data dilakukan dengan menggunakan rumus uji-t. Berdasarkan uji normalitas dan homogenitas kedua kelas berdistribusi normal dan homogen. Pengujian uji-t diperoleh hasil uji hipotesis yang menunjukkan . Maka dapat diambil kesimpulan Ho ditolak dan Ha diterima, berarti ada pengaruh yang signifikan antara demonstrasi alat peraga terhadap pemahaman konsep matematika siswa pada materi bangun ruang sisi lengkung di kelas IX MTs. Muhammadiya 22 Padangsidimpuan.
